V e may prefer to pass each of the cables 18outwardly of they raft under a side boom 2 and from thence over the raftto be ultimately attached to the opposite side boom 2. 19 and 2O arefurther cables laid between the tiers 5 and 6, and 6 and 7, which arelaid out in a manner' similar to those before mentioned. Simultaneouslywith the building up of the several tiers of logs and the laying of thecables therebetween we lay a plurality of chains 21, 21fL and 21h, oneabove the `other underf the vfloor tier 1 and betweenl dierenttiers oflogs adjacent the forward and afterv ends of the raft, as shown in Fig.2, the ends of each tier being fastened outside the raft tothe chainabove it by clips 23, the topinost chain 21b having its ends brought lupover the top tier of logs and fastened together with a clin 23. 22 arefurther chains having an eye at one end which is connected to thelowermost. chain 21 and is passed tightly around a side boom 2 and isclipped at its Y upper end to the chain 21a. Vhen the several tiers oflogs are laid up the free vends .of the cables 9, 18, 19 and 2O arepassed over ythe top of the raft in opposite directions and are passedaround the side. booms 2 and suitably clipped upon themselves.

1 28 are slots through both legs of each shackle in which a bolt 29 isinserted to ing strain of thetug o-n the tow line 15 is transmitted tothe side booms 2 through the line 13 and also to the inner ends of thecentre sticks 10 through the line 17 tending to draw the sticks 10endwise towards each other, any such movement of the centre sticks willsimultaneously draw the looped ends `of the ropes 18 `towards thelongitudinal centre of the raft thereby effecting an Vincreasing bindingstrain upon all the logs that they each encompass. The centre sticksbeing tapered-will on being -drawn inwardly byy the towing action imposea wedging strain upon the logs forming the raft, thus further tighteningthe several bindings around the raft.

When the raft is to be broken up it suffices to withdraw the bolts 29from the clips 23 and disconnect the several cables,

`when the raft will spread apart allowing the logsto come vto restv inthe water.
